It is rare to find dolomite thus used, but the results in Alabama seem to show that magnesia will remove the sulphur as successfully as lime.
COAL AND COKE.
The principal coal deposit in Alabama is known as the Warrior field, which raises 85 per cent, of the output of the State, the chief centers being in the counties of Jefferson, Walker and Tuscaloosa. Most of the coal will give a fair coke, but it is necessary to wash it to remove both sulphur and ash. There was a time when fur-nacemen talked of a fuel ratio of ton per ton, but that day has gone by, and it is now considered good work if a ton of pig is made with 1.3 tons of coke, while the average is higher.
PIG-IRON.
The pig-iron of Alabama has been sent to all parts of the country and much of it abroad. There is a limited demand in the State, but quite a market in Northern cities, as, for instance, Cincinnati, and a great deal is sent by rail and water to Philadelphia, New York and other seaboard points for foundry purposes. Some is carried into the iron districts of Pennsylvania for puddling. The freight rates are low, but the distances are great. The cost of foundry iron in Alabama is usually placed at from seven to eight dollars per ton, and the freight tq Northern points is four dollars and even more. The natural answer to this condition is to manufacture the iron on the spot into finished products, and the making of steel ia the most attractive field.
